A cylindrical tank of capacity 64π litres has equal height and radius. What would be the radius of the cylinder?
(1 litre = 1000 cm3)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 40 cm
Given that
The height and radius of a cylinder are equal i.e. h = r
The volume of a cylinder = π r² h = 64 π ×1000
π r² × r = 64 π ×1000
r = 40 cm
